  • Publication number: 20210020549
    Abstract: A semiconductor package includes a first lead with first and second ends extending in the same direction as one another. At least one second lead has first and second ends and is partially surrounded by the first lead. A die pad is provided and a die is connected to the die pad. Wires electrically connect the die to the first lead and the at least one second lead. An insulating layer extends over the leads, the die pad, and the die such that the first end of the at least one second lead is exposed from the semiconductor package and the second end of the first lead is encapsulated entirely within the insulating layer.

  • Publication number: 20200194345
    Abstract: A leadframe comprising a plurality of leads, each of the plurality of leads having a proximal end and a distal end opposite the proximal end, the distal ends positioned along a linear axis. The leadframe further comprises a die pad closer to the proximal ends than the distal ends of the plurality of leads and including an edge positioned along a plane that intersects the linear axis at an angle less than 90 degrees.

  • Publication number: 20190355652
    Abstract: In an example, an apparatus comprises a lead frame that includes a first row of leads, a first pad coupled to the first row of leads, and a second row of leads parallel to the first row of leads. The lead frame also includes a second pad coupled to the second row of leads. The first and second pads are separated by a gap, and each of the first and second pads has a substantially uniform thickness. The apparatus also includes a device coupled to the first and second pads. The first and second pads are exposed to an exterior of the apparatus.
